Development of computer models to simulate the mechanical regulation

Although bone is able to self-repair, in many situations its regener6ation capacity is impaired, leading to delayed or non-unions. The healing process is known to be influenced by many factors; among them mechanical signals have been shown to play a fundamental role. In the Computational Mechanobiology Group, we are interested in understanding the mechanical "rules" driving bone regeneration processes. We develop computer models to simulate the mechanical regulation of cellular activity and its consequences at the tissue level.
